What is the price of Neon ?

At this point Neon is free ... and it is a good tool .. it is slightly jumpy on my machines as it has to create a raytrace each time its moved ... so for most work I would rather use the display built in to MoI.

It's pretty peppy on my new machine.

I also use MOI and Rhino together and have already upgraded to V5. I work with large mesh files (resulting from 3D scanning) and for me the 64bit version is worth every cent of the upgrade price.

Why MOI? I use it during the prototype stage of a project. I really like the speed with which I can create a concept model then dump it (via stl) to my 3D printer.
